摘要： The present invention relates to a process for preparing enzymatically debranched starch by mixing natural starch, water and polyalcohol to form a starch mixture, adding α-1,6-D-glucanohydrolase to debranch the natural starch under 50˜70° C., and terminating the debranching reaction by increasing the temperature of starch mixture. The process of this invention can achieve the purpose of degrading starch to lower molecular weight, while raising amylose content of starch so that the plasticity of starch is increased.
